Young Wrestler Exercise Tips PLEASE!

I'm doing a case study and could really use some help. Because the client is so young, I'm not sure exactly how to start out. If anyone has advice, I'd greatly appreciate it.

This is the information provided:
Chris, 14, 120 pounds, 9% body fat, is a high school student and is eager to gain some muscle mass. He eats a diet that consists primarily of processed foods (fast food, cafeteria, etc.) Chris is anxious to get stronger so that he can go out for the wrestling team.

A little vanity, mostly for his wrestling potential though (it's a mock case study, so it's hard to tell!!). So I shouldn't put him through a periodized plan? (hypertrophy to strength to power to peaking?)

At 14 he should be able to make linear gains for a good while. A few resets/deloads here and there.

As Kik stated, teaching form with just the bar would be optimal in the beginning, then start loading, probably after a couple of weeks of bar only drills. Really, at 120lbs the bar might be the starting point on a number of movements anyway. Perhaps a broomstick handle could be used instead.

To gain muscle, it is going to be all diet. The diet must be cleaned up or the kid will gain alot of fat as he'll have to be eating in a caloric surplus.

"225, 315, 405 whatever. Yeah these benchmark digits come to mean a lot to us, the few warriors in this arena. They are, however, just numbers. Iím guilty of that sh*t too, waiting for somebody to powder my nuts cuz I did 20 reps of whatever the **** on the bench. Big f*king deal. It is all relative." G Diesel

You can, and you will if you are interested in making serious progress.

The reason being the question says to make a periodized program. Hence not the same for 12 weeks even though I agree that he will keep improving but just to follow the question guidelines says he shouldnt.
